Ashcroft pressure temperature and control instruments are specifically designed to meet the demands of the water treatment and wastewater industries; and along with our high quality, rugged instruments, Ashcroft provides detailed documentation for your critical engineering and compliance requirements.

Pressure Gauges for water treatment and waste water industries.

Pressure Gauges:
Designed to meet the rigors of water treatment and wastewater applications, the family of Ashcroft dry, liquid filled and PLUS Performance pressure gauges is unsurpassed. Ashcroft Duragauge process gauges have long been the benchmark when a solid front, ASME grade 2A, ½% accuracy pressure gauge is required. Standard exclusive features like a 400 Series stainless steel movement for longer life, and the patented Duratube Bourdon tube for superior strength are just a few of the reasons these gauges outlast other gauges in the market place.

When pulsation and vibration are present in the process, the patented PLUS! Performance option provides the performance of a liquid filled gauge, all in a dry gauge. PLUS! Performance dampens vibration and pulsation, providing an easy-to-read gauge with no fill lines and a steady pointer. PLUS! Provides a wider temperature range over glycerin fill and eliminates costly specialty fluids, as well as the added expense for disposing of a liquid-filled gauge.

Stainless steel case gauges are offered with rugged, all welded socket-to-case design for superior strength. When vibration and pulsation are a factor, these gauges are also available with our patented PowerFlex movement for improved shock resistance.

When a superior, low cost commercial-type gauge with bronze wetted parts is a requirement, Ashcroft commercial gauges are available with the PowerFlex movement as well as True Zero indication. With True Zero indication you can be certain that if your gauge reads zero-there truly is zero pressure in your system.

You benefit with increased safety, and reduced replacement costs.

Differential Pressure Gauges:

Design to measure the difference between two pressures across filters, strainers or separators, Ashcroft dp gauges offer a unique combination of Bourdon tube design and flexible diaphragm designs. Together, these features provide you with the best value to measure differential pressure on critical applications.
